Sooo my car sat forever, pump is dead and it's caked full of shit... this is the high pressure external pump not the in-tank pump (I got rid of that a while back). The pump has 0580254967 on the outside, it looks like I can get it from summit still: https://www.summitracing.com/parts/bch-0580254967

But Rockauto and other places list 69466 as the replacement, what are the differences if any?
